I am going through my bike after a long summer break and I am behind on getting it put back togther. I needed to replace my entire drive system, after much thought and I decided to go back with aluminum rear sprocket after much debate within myself. I know that many of you guys like and use the Dirt Works Ironman drive systems, so I choose another route. My last set of sprockets were trashed. I had used AFAM rear with great results, much better over using the PBI which is what I am replacing now.
I ordered a kit, AFAM Workslite rear in a 51 tooth and the AFAM counter shaft 13 tooth and for the chain I went with the RK 520 XSO 120 links /with clip style masterlink.
I ordered everything from
http://www.sprocketcenter.com/ for a very good price.
Rear Sprocket PN# 15206+51 for tooth size
